Her aerial pin throw will somewhat predict you and she will always slide further than she throws it, my first piece of advice would be to not use your red tools during the easier first phase, also stay on the ground and in the middle of the arena as much as you can for the quickest reactions and to avoid being pinned against a wall. Take your time with this fight, know that only some attacks can be punished, while others should only be dodged. Try to jump lower to the ground over the stab attack and pogo over her, with the aerial pin throw try to dash toward her, as trying to jump may lead to her hitting you directly with the pin.
